According to Griffing's method 1, diallel crossing was built and CA was analyzed. Variance analysis showed that there were the greatly significant difference among the both of GCA in inbreeds and SCA in crosses, respectively. The high GCA of 18-599 and 18-599 and the low SCA variance of their crosses showed the strong and stable heredity on the both characters. Taking them as parents, the generations with high and stable induction and regeneration will be gotten.

According to the method, model dimension is contracted to five by the way of selecting the unit in which amount of I/K is m inimal. Then sensitivity of frequency to stiffness is calculated. After the diff erence between measured frequency and calculated frequency have been got, the ad justed amount of stiffness is calculated by the using of the sensitivity and the frequency difference.
该方法按照I/K最小优先合并原则,将轴系模型自由度数缩聚为5,分析该模型4个刚度对前4阶频率的敏感度,算出实测的前4阶频率和模型计算频率之间的差值,利用敏感度和频率差值计算出刚度的调整量。
